Raspberry Pi 2 running custom Satcom software
Windows 7 PC (shared) running SDR-Console/Server, remote accessible via VNC
Control Systems
Windows 7 PC (dedicated) running SDR-Console/Server, remote accessible via VNC
Two Mac Mini’s located in the main lab act as control terminals. Each Mac Mini is running MacDoppler software which can connect to any of the three stations over the network to control radio tuning and antenna positioning if desired for more user-interactive control.
All stations can be remotely controlled via SSH to the Raspberry Pi’s, or remote desktop (VNC) to the Windows 7 PC’s or Mac Mini’s.
Remote Control and Automation
The Raspberry Pi’s also call home to a primary Satcom server which handles pass scheduling and automated commanding and downlink from our latest generation of satellites, independent from the Windows 7 PC’s or Mac Mini’s. The Satcom server can be tasked using a custom iPhone app.
